In posterior view, the carapace apex is rugulose-lacunose and bears a small transverse carina directly above the posterior margin of the carapace. In lateral view the carapace is more than 4 xas long as wide. Head black-brown; mesosoma mostly orange with some brownish black areas; carapace black with yellowish white elongate oval area baso-medially between dorsal carinae. Presence of the wide foveate groove at the precoxal sulcus.  Figures 24-28. Leptodrepana demeter. 24 Female habitus in lateral view 25 female habitus in dorsal view 26 metasoma in dorso-posterior view terminating rounded 27 metasoma in lateral view 28 metasoma in dorsal view.  Holotype female. BL 3.4 mm; FWL 3.06 mm; CL 1.92 mm; CW 0.4 mm; CL/CW 4.8.  Description. Color. Head black/brown, mandibles mostly yellowish brown but black/brown basally and apically; palpi yellowish white; antennae brown except scape, pedicel and base of first flagellomere yellowish white; mesosoma mostly orange with some brownish black areas on median pronotum (visible laterally), mesopleuron postero-ventrally and over the median flanges of the propodeal carina; legs mostly yellow, hind leg with brown areas apically on coxa and femur and white patch laterally on femur, tibia with distinct pattern: linear white ellipse ringed in brown visible dorsally running most of tibial length; wings suffused with light yellow/brown pigmentation; venation brown but veins 1M, RS+Ma, 2RS and 2M yellow or light brown; carapace black with yellowish white elongate oval area baso-medially between dorsal carinae. Head. HW 0.95 mm; HL 0.83 mm; HW/HL 1.15; face, genae, vertex and ocellar triangle rugulose-punctate; frons depressed, impunctate with fine parallel lineation transverse to median carinae; clypeus rugulose-punctate and apical margin rounded; occipital carina complete. Mesosoma. Pronotum foveate antero-laterally to weakly areolate-rugose to smooth postero-laterally; propleuron weakly areolate-rugose; mesoscutum medially with 2-3 irregular parallel pitted grooves between notauli; notauli distinct and visible anteriorly; mesonotal lobes granulate-punctate; scutellar sulcus with five well-defined depressions, all longer than wide; scutellar disc punctate; mesopleuron anteriorly rugose and medially foveate; precoxal sulcus with a wide foveate groove; propodeum coarsely areolate-rugose with distinct transverse carina raised into small roughly equal medial and lateral flanges. Metasoma. Carapace areolate-rugose basally graduating to rugulose-lacunose at apex; in dorsal and lateral views, carapace apex rounded; in posterior view, apex rounded and bearing a small transverse carina directly above the posterior margin of the carapace. Variation of paratype females. Color: apical margin of clypeus brownish orange; carapace small baso-medial area of brownish orange; HW 0.85-0.88 mm; HL 0.68-0.73 mm; HW/HL 1.2-1.26; BL 2.86 mm; FWL 2.33 mm; CL 1.4 mm; CW 0.32 mm; CL/CW 4.37. Paratype males. No males.  Material examined. Holotype female: GUANACASTE, Arenales W. side Volcan Cacao, 900 m, 1988-1989 (P. Hanson) [UWIM]. Paratype females: 1♀, same province, Est. Pitilla, 9 km S Santa Cecilia, 700 m, v.1989 (I. Gauld); 1♀, same data except iv.1989.  Remarks.  Leptodrepana demetermay be confused with L. condaas both females are similar in color and have a rounded carapace apex. It may be distinguished from L. condaby presence of the wide foveate groove at the precoxal sulcus as opposed to a scrobiculate groove in L. conda. In posterior view, the carapace apex of L. demeteris rugulose-lacunose and bears a small transverse carina directly above the posterior margin of the carapace. Whereas in posterior view, the carapace apex of L. condais weakly areolate-rugose. When viewed laterally, the carapace of L. demeteris more than 4 xas long as wide. In L. condathe carapace is not more than 3 xas long as wide. Additionally the propodeum of L. demeteris mostly orange and the baso-median patch of yellowish white, when present, does not extend to the lateral margins of the carapace. The propodeum of L. condais blackish brown and the basal third of the carapace is completely yellowish white. Superficially L. demeteralso resembles L. atalantain color and size. However, the apex of L. demeteris rounded in dorsal view (Figs 26, 28), while the carapace apex of L. atalantamay terminate in a single pointed or truncated end (Fig. 10, 11).  Etymology. This species name stems from the Greek Demeterrepresenting the goddess of agriculture, sister of Zeus, and mother of Persephone.
